This geometry would work: https://www.youtube.com/watch?v=1EYaM4FkASA Forget the XY axes, imagine a mini-lathe rotating slowly under stepper control where the table is, and the spindle rotating on the saddle. (no cross-slide, pivot point exactly on the centre line) Start with the spindle coaxial with the spindle, push the work to the milling cutter, clamp the chuck then slowly rotate the work while the spindle swings to 90 degrees. You would need a "W" feed to alter the working radius. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
